Hello,

i want to use the Open-E Snapshot Technology for backup.
A short overview about that what i want to do:

I have a System that doesn't have enough HDD space for a complete backup of its database.
For that i connected the server to an iscsi storage.
Now i would backup this db.
But i want backup from another server which has been connected to a LTO library.
My plan was, that i do a read-only snapshot of the LUN and mount the snapshot to the backup server, so i backup from iscsi over the backup server direct to tape.
I think, that i've done the snapshot correctly.
On the backup server side i see 2 LUNs with the same amount of space. (in my case 140 GB)
The first one LUN is the read-write LUN that ever existed on the target.
After the snapshot, i see a second LUN. But when i want to mount the second LUN, i didnt see any file system.
I tested 2 versions of backup server systems, a windows and a linux system.
On linux system, when i try to mount i see the following error:
mount /dev/sdc1 /mnt/orbix14-SS/
mount: block device /dev/sdc1 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Is it possible that i have an error in my plans?
Does i musunderstood the Snapshot Feature?
How can i mount/connect a read-only snapshot for backup purposes?

Thanks...
